Question

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string.
Ex: If the input is: n Monday,
the output is: 1
Ex: If the input is: z Today is Monday,
the output is: 0
Ex: If the input is: n It's a sunny day,
the output is: 2
Case matters. n is different than N.
Ex: If the input is: n Nobody,
the output is: 0

Your program must define and call the following function that returns the number of times the input character appears in the input string.

int CountCharacters(char userChar, string userString)

Answer 1

Answer:

The program written in Java is given in the explanation section

Explanation:

public class num9 {

//Defining the method CountCharacters()

   public static int CountCharacters(char userChar, String userString){

       int c = userString.length();

       int count=0;

       for(int i=0; i<c; i++){

           if(userString.charAt(i)==userChar){

               count++;

           }

       }

       return count;

   }

//Main method begins here

   public static void main(String[] args) {

   char n ='n';

   String word = "Monday";

//Calling the method CountCharacters()

       System.out.println(CountCharacters(n,word));

   }

}
